THE KNICKER- DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 404,217, dated May 28, 1889.

Application filed November 5, 1888. Serial No. 289,957. (No model.)

To all whom it may concern:

Be it known that I, ORVILLE M. MORSE, of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Dust-Collectors, of which the following is a specification.

This invention relates to that class of dustcolleetors which contain a separating-chamber having an imperforate peripheral wall to in which the dust-laden air-current is caused to assume a whirling 0r gyrating motion by means of a tangential inlet-spout or otherwise, whereby the dust particles are driven against the peripheral wall, while the air which has been freed from dust escapes through a central openingin one of the ends of the separating-chamber.

The object of the present invention is to produce a simple and efficient. dust-collector of this kind; and my invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section of my improved dust-collector. Fig. 2 is a bottom plan view of the same. Figs. 3 and 4 are vertical sections showing modified forms of myimproved dustcollector.

Like letters of reference refer to like parts 0 in the several figures.

A represents the imperforate peripheral wall of the separating-chamber, which latter is preferably tapering in form, as shown.

B is a tight head which closes the large end 3 5 of the tapering separating-chamber and to which one end of the peripheral wall is secured.

0 represents the inlet-spout for the dustladen air-current entering the separating- 40 chamber tangentially through an opening formed in the peripheral wall near the tight head 13.

D is an annular head which is secured in the small end of the tapering separatingchamber and provided with a central opening, d, through which the air escapes from the separatingchamber. This opening is provided with a tubular guard, e, which projects into the separating-chamber in a wellknown manner and tends to prevent dust particles from escaping with the air.

f represents the dust-escape spout, which communicates with the separating-chamber at the same end at which the air-escape opening (1 is located, and which is arranged between the tubular guard e and the peripheral wall of the separating-chamber. This dustspout may be provided with a relief-pipe, g, as represented in Fig. 4:, which returns the greater portion of the air which escapes with the dust into the inner portion of the separating chamber by reason of the suction created in the center of the vortex.

When the dust-collector is designed for catching very fine or adhesive dust, it is preferably provided with an automatic cleaner, as represented in Fig. 1. This cleaner is provided with wings, sweeps, or brushes h, which sweep the inner side of the peripheral wall and the space between the tubular guard and the peripheral wall, thereby preventing the accumulation of dust on the annular head D. The wings h are attached to a central shaft, 1;, by arms j, and are preferably made so large that they are rotated by the whirling body of air. A wing, sweep, or brush, it, may also be arranged in the tubular guard to keep the inner surface thereof free from accumulations of dust.

WVhen the dust-collector is designed for catching coarse material-for instance, sawdust, chips, &c., from wood-working machinery-the peripheral wall is preferably pro vided on its inner side with a spiral flange, Z, which directs or deflects the material toward 5 the dust-discharge spout, as represented in Fig. 3.

I claim as my invention- 1. A dust-collector having an imperforate peripheral wall, an inlet for the dust-laden 96 air arranged to cause a whirling motion of the air and dust in the separating-chamber,

a tight head closing one end of the separating-chamber, and an outlet for the air freed from dust and an outlet for the separated dust, both arranged at the opposite end of the separating-chamber, substantially as set forth.

2. A dnstreolleotor having a tapering imend of the separating-ehamber, substantially perforate peripheral Wall, an inlet for the as set forth. I O dust-laden air arranged to cause a whirling itness my hand this 29th day of ()(il-Ubfil', motion of the air and dust in the separating- 1888.
